That's all it does Frank, and you don't really want more than that.
I've read a bunch of articles about charging batteries, namely AA'S, they talk about the max being 1C, which is 1x capacity. But, I've read in the Panasonic website about charging their 18650's to only charge at 500mah. Since the Panasonic's are Japanese cells, that's what I'm sticking with. If i need to go quicker, 1000mah will be fine.
I picked up some of the new Panasonic batteries, 3100's and 3400's, and they both make or exceed their capacity. These are the ones that hard_ware listed, the 3100's and I also got 6 more is the 3400's that they now make.
Going to be nice running with these.
Have you checked capacity on your batteries Frank?

there is a way to read capacity, discharge them and see what mah they get, then charge them and see what they get, can also do a refresh, which will take awhile going through cycles of discharging and recharging....my 3100 does this, I'm assuming the 3400 analyzer you picked up does the same thing
I read the instructions and have played with it, reads nothing over 2000, after reading on the internet there is not a meter to read Mah, there are math formulas you can guesstimate. My thought is the Chinese are slapping 5000 MaH on a battery and knowing they are not. All I know is the 3K and 5K MaH batteries I have run a lot longer than the 2400 I started with, how much longer? I don't have the hours to check and worry about that, I just carry spares.

I was just reading the manual Frank, you can charge 2000mah in slots 1 and 4, only 1000mah in 2 and 3, but will display capacity in all slots....
so, put in your batteries, I like to unplug the power cord, put in all batteries, plug in cord, then hit the mode button until it reads discharge....discharge your batteries, will tell how much was in each battery at current charge, then unplug again when it says its down, run a charge on them, then use the display button to see what mah they are at when full/done

it does read it Frank, do as I said above...
I'll even show you, i'll take some batteries, discharge them and show capacity they were at, then I charge them full and show that capacity, will post pics later today
Uh, Frank, have you noticed what the American politicians, American car companies, American chemical companies, American drug companies, American drilling companies, the CDC, etc. have been doing? How about ATN? Remington? For years, Surefire claimed that its 100 lumen flashlight was a type of weapon because it was so bright.
The Chinese do not have a monopoly on misrepresentation and lying.
One thing I do know is that while many people can test battery performance, few people have the tools to actually and accurately test light performance, especially lumens.

I like the AW brand, although I think the 3400s may be a little too long for my olite M1X with battery extender. The positive terminal is getting indented. Probably just shorten the spring or something like that? 3100s fit fine. And 3400 singles in other flashlights fit fine
It may have just been a combination of bad charger but I initially was using the ultra fire battery and the ultra fire charger and I was not able to recharge these batteries more than about two or three times and most of the time they wouldn't even fully charge. Was very frustrating.
I am now using the Pila charger with the AW battery and have multiple recharge cycles on them and I am very happy with the set up.

yea the Chinese just lie more, lumens, capacity, function, etc.
there is no way to put a battery in anything and read the capacity instantly, that's why you need to discharge a fully charged battery to read capacity, or charge a fully discharged battery to read capacity
one of the tests to see how my LSD (Low Self-Discharge) batteries to see how they hold charge over time is charge up several of them, then let them sit and discharge one after a month to see how much charge it had remaining, then maybe another the next month or several months later....

if you saw my post earlier in this thread, my Ultrafires are junk, the 2600, 3000 and 5000 mah batteries all get the same, about 1000mah or less....
